1.1 Functional description
The modules dose the power at the vibrating magnets through phase angle without further control. The setting of
power is done with a potentiometer, analogue reference 2 to 10 Volt DC or analogue constrained-current operation 0 to
20 mA. The aforementioned reference value allows line lengths of more than 10 meters, otherwise the max length of
the line is 3 m. When operating between heavy interference centres, the control wires should be shielded.
The output voltage for the smallest reference values 0 Volt (potentiometer at the left catch) can be selected with the
trimming potentiometer between 0 and 90 Volt (eff.) The highest output voltage at the reference vale 100 % can be set
with the trimming potentiometer Umax between 150 and 220 Volteff.
An enable input allows the module to be switched on and off wattless. Enable can be done with a normally open
contact or voltage signal 12.....24 Volt DC. The connections for the reference value and enable are free from the mains
potential.
Pins 19 and 20 are made available for the operating mode. If these pins are bridged, the module is working on sym-
metric full wave. The vibration is then working with double the mains frequency. A missing connection leads to an
asymmetric half wave, so that the vibrating drive is working on the mains frequency.
The fuses are accessible from the front panel. It is a microfuse 5x20 mm. The value for the module ESM 906 is 10 A
super quick. This fuse is only to protect the internal semiconductor. An overload fuse to protect the complete
unit has to be done external (i=6A).
The module ESM 910 has now own fuse, but it has a short-circuit-proof on the main power supply unit.
The modules are provided with a fixed preset soft start.
Set-up
The modules have, at the left side wall, a heat dissipation plate for the power semiconducter. Therefore it is necessary
to have a free space of a least 50 mm to the next appliance for heat dissipation.
